qlcnic_init.c:1854: warning: unused parameter sds_ring
qlcnic_init.c: In function qlcnic_fetch_mac
qlcnic_init.c:1938: warning: unused parameter adapter

warning: 'pci_using_dac' may be used uninitialized in this function [-Wmaybe-uninitialized]
qlcnic_main.c:1569:10: note: 'pci_using_dac' was declared here
